If you use `require` or `use` (the latter is usually preferred) then said warning shouldn't occur. Perl keeps track of which modules it has already compiled, and won't recompile a module unless you know which strings to pull. That is, as long as you use `require` or `use`. Note that the manual page about `do` also recommends the use of `require` or `use`. Abigail	[reply]

I suspect that you have the same function names in different modules. Also, if you're useing or requireing, don't do. In fact, don't ever do. I have used do in production code to source in files exactly once in my career, and the file that was done had one (large) configuration variable in it. (That hack was removed in a later version.) do skirts too many safeguards, such as the built-in #ifndef mechanism that use and require provide. ------ We are the carpenters and bricklayers of the Information Age.

but I can't just do: `use 'test.pl'; # or use 'test.ph';` [download] It shouts for syntax error, use argument suppose to be a module name, not a file name, so what else can I do? Hotshot	[reply] [d/l]

Try require, then. Or, rewrite test.pl so that it fits the model for use. (I recommend the latter, simply because it's generally better.) ------ We are the carpenters and bricklayers of the Information Age.
